What is achoo?

"Achoo" is an onomatopoeic word used to describe the sound of a sneeze. It is typically associated with the common cold or allergies. Sneezing is a reflex action that occurs when the mucous membranes in your nose are irritated. When you sneeze, air is forcefully expelled from your nose and mouth, which can spread germs and allergens to those around you. It is recommended to cover your mouth and nose with a tissue or elbow when sneezing, and to wash your hands regularly to prevent the spread of illness.
